Write, delete and rewrite as many times as you like - that's the beauty of Pilot FriXion pens! But just how can ink seemingly be written and then effortlessly removed without trace? Well, with FriXion's exclusive thermo sensitive ink technology, mistakes can be corrected with ease using the integrated FriXion eraser tip which works in the same way as a regular pencil eraser. No mess, no dust, no paper damage and completely 'erased' lines. Re-write over using the same pen!
